Embodiment 1

[0015] A kind of production process of the foamed ceramic insulation board that ceramic fiber paper reuses, comprises the following steps:

[0016] (1) Mixing and grinding: Calculated in parts by mass, pour 45 parts of raw clay, 20 parts of diatomaceous earth, 32 parts of quartz sand, 2 parts of foaming agent, and 18 parts of lime into the grinder, and add water for grinding. When particles with a particle size of less than 60 μm account for more than 80%, add the waste ceramic fiber paper obtained in the subsequent firing step. Calculated by mass parts, the amount of waste ceramic fiber paper added is 0.1% of the raw material, and then continue grinding , until the particle size of the material after mixing and grinding is less than 40 μm, and a slurry is obtained.

[0017] (2) Pour the slurry into the mold and dry it.

[0018] (3) Firing. Put the foamed ceramic insulation board together with the mold into the firing furnace. The firing temperature is 1230°C. During firing, ...

[0021] A kind of production process of the foamed ceramic insulation board that ceramic fiber paper reuses, comprises the following steps:

[0022] (1) Mixing and grinding: Calculated in parts by mass, pour 35 parts of raw clay, 30 parts of diatomaceous earth, 15 parts of quartz sand, 8 parts of foaming agent, and 10 parts of lime into the grinder, and add water for grinding. When the particles with a particle size of less than 60 μm account for more than 80%, add the waste ceramic fiber paper obtained in the subsequent firing step. Calculated in parts by mass, the amount of waste ceramic fiber paper added is 3% of the raw material, and then continue grinding , until the particle size of the material after mixing and grinding is less than 40 μm, and a slurry is obtained.

[0023] (2) Pour the slurry into the mold and dry it.

[0024] (3) Firing. Put the foamed ceramic insulation board together with the mold into the firing furnace. The firing temperature is 1210°C. During fir...

Abstract

The invention relates to the field of materials, particularly to a production process of a foamed ceramic thermal insulation board by recycling ceramic fiber paper. The process comprises: mixing and grinding, drying, firing, and cooling, wherein in the firing step, the temperature of a firing furnace on the inner wall of the firing furnace is kept by using ceramic fiber paper to obtain waste ceramic fiber paper, and in the step of mixing and grinding, the waste ceramic fiber paper is added into raw materials. According to the invention, thermal insulation is performed by using ceramic fiber paper in a firing process so as to reduce energy consumption, and the fired waste ceramic fiber paper is added into raw materials, so that waste is utilized, and the mechanical strength of the foamed ceramic thermal insulation board can be improved.

Description

technical field [0001] The invention relates to the field of materials, in particular to a production process of a foamed ceramic insulation board for recycling ceramic fiber paper. Background technique [0002] The existing foamed ceramic insulation board is a high-porosity closed-cell ceramic made of clay tailings, ceramic fragments, river silt, adulterated materials, etc. Material. The product is suitable for building exterior wall insulation, fire isolation belt, building self-insulation cold and heat bridge treatment, etc. The product is fire retardant, small deformation coefficient, anti-aging, stable performance, good ecological environmental protection, good compatibility with wall base and plastering layer, good safety and stability, and can last the same life as the building. More importantly, the fireproof grade of the material is A1, which overcomes the Achilles heel of organic materials, which are afraid of open flames and is easy to age, and fills the domesti...
